Software reuse: experience and approach in the development of business process controllers

A five-step approach to maximizing software reuse at each phase of the software development life cycle is presented. Some boundaries of software reuse are also discussed. The CRTF (Controller Reuse Task Force) investigation revealed that, if redundant efforts for shaping the architecture and solving the functional needs of all the identified business process controller products were eliminated and reusable solutions were developed, then an approximate overall resource savings of more than 50% could have been realized in each controller product development effort
